s thermal power generation. By the end of 2018, a total number of

440 large-scale CFB boilers with capacity of above 100MW (410 t/h) had been put into operation in China, and the total installed capacity had exceeded 82.3 GW. The unit capacity, installed scale and technological advancement of CFB boilers have reached the world'

s leading level. The development history and application status of CFB boilers in China, and analyzes the application fields, main models, unit distribution, major technical and economic indicators in recent years are introduced. From the perspective of capacity parameter, technology standard system, international application, operational flexibility, fuel adaptability and so on, the development of CFB boiler technology in China is forecasted.
